Definitions
- the invention relates to a method for sampling acceleration measurements of a wheel of a motor vehicle equipped with a tire pressure monitoring system.
- More and more motor vehicles have, for safety purposes, tire pressure monitoring systems comprising sensors mounted on each of the wheels of the vehicle dedicated to the measurement of parameters, such as pressure and / or temperature of the tires. equipping these wheels and intended to inform the driver of any abnormal variation of the measured parameter.
- These monitoring systems are conventionally equipped, on the one hand, with electronic boxes (also called wheel units) mounted on each of the wheels of the vehicle, and integrating, in addition to the aforementioned sensors, a microprocessor, a radio frequency (RF) transmitter and an antenna LF ("Low Frequency" in English, low frequency), and secondly, a central unit (mounted on the vehicle) for receiving the signals emitted by the transmitters, comprising an electronic computer integrating a connected radio frequency receiver to an antenna.
- electronic boxes also called wheel units mounted on each of the wheels of the vehicle, and integrating, in addition to the aforementioned sensors, a microprocessor, a radio frequency (RF) transmitter and an antenna LF ("Low Frequency" in English, low frequency)
- RF radio frequency
- LF Low Frequency
- Such monitoring systems require the obligation to associate with each signal received by the receiver of the central unit, information concerning the location of the transmitter electronics unit and therefore the wheel at the origin of this signal, this obligation continuing during the life of the vehicle, that is to say, to be respected even after wheel changes or simply inversions of the position of these wheels.
- LF low frequency radio antennas
- the central unit sends low frequency signals successively to each of these antennas to excite them.
- the electronic unit mounted on the wheel located near the excited antenna transmits in response to and towards the central unit a signal comprising an identification code of said housing, so that the successive excitation of the three antennas leads to the location of the three electronic boxes mounted on the wheels adjacent to these antennas, and by deduction, to the location of the fourth housing.
- a vehicle 1 equipped with an ABS system and a tire pressure monitoring system, comprises:
- ABS sensors 100, 200, 300, 400 located facing each of the wheels 10, 20, 30, 40 of the vehicle 1, measuring the rotational speed of each of these wheels V A , V B , V c , and V D , and connected to a central unit 2 via a CAN network ("Control Area Network" in English, or serial system bus),
- wheel units A, B, C, D located on each of the wheels J10, J20, J30, J40 of radius R of the wheels 10, 20, 30, 40, measuring the radial acceleration of these wheels and connected by RF to the central unit 2.
- the ABS sensor located next to the wheel locates each tooth of a toothed target located on the wheel, the teeth are equidistant and therefore represent the angular position of the wheel at a given moment.
- the wheel unit As for the wheel unit, it sends a signal to the central unit at a fixed position on the wheel.
- the wheels 10, 20, 30, 40 fitted to the same vehicle 1 do not all rotate at the same speed V A , V B , V c , V D , it depends above all on the trajectory of the vehicle 1 (in this case bends), but also wear, and tire pressure as well as slippage effects (braking and / or accelerations). It follows that the fixed initial transmission position of the wheel unit shifts for each wheel after a few turns of the wheel.
- the central unit 2 deduces the transmission position of the wheel unit on the wheel as well as the right front position, rear right ARD, front left AVG and rear left ARG wheel units A, B, C, D.
- the wheel unit belongs to the wheel whose ABS sensor constantly locates the same transmission position on the wheel of the wheel unit; the position of the ABS sensors, 100, 200, 300, 400 being fixed on the vehicle 1 and known by the central unit 2.
- the wheel unit thus determines the torque (ABS sensor, wheel unit) which indicates the same angular emission position.
- ABS sensor wheel unit
- This wheel location method is reliable and robust, however the major problem is to ensure that the wheel unit always emits at the same position on the wheel.
- the radial acceleration sensor of the wheel unit measures the radial acceleration several times over one wheel revolution. This is illustrated in FIG. 2.
- the wheel unit A located on the rim J10 of the wheel 10 comprises an accelerometer (not shown) which measures the radial acceleration that it undergoes at various positions on a lap. wheel, when the wheel rotates in the direction of rotation W, that is to say at the positions Pi, P2, Pj, P3, Pk, P4, P. These measurements are preferably made at a fixed frequency.
- the force of acceleration measured by the radial accelerometer of wheel unit A is the resultant of two radial components, a force F 1 , which is the projection of gravity g along the direction of measurement z of the radial accelerometer and a force lv which is the projection of the centrifugal force F v , according to this same measurement direction Z of the radial accelerometer A, thus:
- ⁇ G represents the gravity constant, it is a vertical vector, directed downwards, of value -9.81 m / s 2 ,
- the curve of the radial acceleration Fi (t) as a function of time is therefore a sinusoid (see FIG. 2b), the maximum MAX and the minimum MIN corresponding respectively to the position of the accelerometer at the bottom of the rim in position. P3 and respectively at the top of the rim in position P1.
- the values of the minimum and maximum of the radial acceleration in position P1 and P3 are not fixed and depend on the speed of rotation of the wheel, this minimum and maximum can therefore be determined only locally at each turn of rotation. wheel and not absolutely in relation to fixed value thresholds.
- a numerical treatment of these radial acceleration measurements by the wheel unit makes it possible to determine the minimum value MIN of the radial acceleration and therefore the passage of the accelerometer to the position P1 and / or the maximum value MAX of the radial acceleration and therefore the passage of the accelerometer to the position P3.
- the processing of the radial acceleration measurements making it possible to determine these positions is not immediate, there is therefore a duration (of treatment) between the determination of the emission position and the emission of the signal by the wheel unit.
- the fixed emission position is therefore located just after, in the direction of rotation of the wheel, these determined positions.
- this time interval may be sufficient to perform a minimum number of radial acceleration measurements. on a wheel spin at low rotational speed or for wheels with a large rim radius, but it may be too big for high speeds rotation or for rays of smaller rims. Indeed, if this interval is too large, then the number of radial acceleration measurements on a wheel revolution is insufficient to be able to determine quickly (that is to say on a wheel revolution) and reliably the minimum or maximum of the radial acceleration, that is to say the fixed transmission positions of the wheel unit.
- a predetermined time interval between two successive measurements of accelerations provided by the radial accelerometer is therefore not desirable.
- This measurement time varies with the speed of rotation of the wheel and, consequently, with the speed of the vehicle, as well as with the radius of the rim of the wheel. In fact, the smaller the radius, the shorter the time required to perform a wheel revolution, and therefore the closer the measurements must be.
- the object of the present invention is to remedy this drawback by calculating a time interval between two successive measurements of radial acceleration, adapted to the speed of rotation of the wheel, to reliably and quickly determine the fixed transmission position. of the wheel unit on the wheel. It should be noted that one of the objects of the invention, illustrated here, is to determine an absolute fixed position of the radial accelerometer (that is to say of the wheel unit) on the wheel and not a relative position.
- the proposed invention relates to a method of sampling acceleration measurement of a wheel of a motor vehicle, said vehicle being provided with a tire pressure monitoring system, and being equipped with an electronic central unit , said wheels each comprising:
- said method comprising measuring, by wheel revolution, at given time intervals (Tmesure), a number (N) of radial acceleration values by the radial accelerometer, and the method according to the invention consists in :
- the accelerometer is a radial accelerometer.
- the invention also relates to the device implementing the acceleration measurement sampling method as described above.
- FIG. 1 is a schematic representation of the tire pressure monitoring system of a vehicle, equipped with an ABS system, according to the prior art
- FIG. 2 (2a and 2b), already explained above, illustrates the sampling of the radial acceleration measurements in order to determine a fixed transmission position of the wheel unit, according to the prior art
- FIG. 3 already explained above, illustrates the decomposition of the forces undergone by the radial accelerometer according to the prior art.
- the duration T of a wheel revolution is given as a function of the acceleration value Fi of a wheel revolution, measured by the radial accelerometer and the radius of the rim R.
- the time interval T measured between two measurements will therefore be equivalent to:
- the advantage of the invention is therefore able to vary the time interval between measurements T e my heart. for example between positions Pj and P3 (see Figure 3) depending on external conditions such as the radius of the rim R or the vehicle speed.
- This method of sampling acceleration measurements makes it possible to maintain a predetermined number N that is considered sufficient to find at each wheel revolution the maximum value MAX and minimum MIN of radial acceleration so that the wheel unit can always transmit to the same fixed position on the wheel.
- the radial acceleration measurements can be filtered (high-pass or low-pass filter) to avoid parasitic measurements resulting for example from a sudden slip of a tire vibrations from the surface of the wheel, or still the vibrations coming from the axis of the wheel.
- the number N of acceleration measurements is set to 15.
- the number of acceleration measurements N is greater than 15.
- the digital processing is defined in order to be able to tolerate variations in the number of radial acceleration measurements N (c ie, samples) per wheel revolution of up to 30% (i.e. N and 10 instead of 15).
- N is crucial. It can be empirical or depend on the signal processing capabilities of the wheel unit; indeed, since the wheel unit must be able to quickly determine the corresponding position (s) at the maximum and / or the minimum of the radial acceleration, the quantity of data, that is to say the number N acceleration measurements to be processed must be limited.
- the invention is not limited to the embodiment described and shown which has been given by way of example.
- the purpose of the sampling method is to determine a fixed transmission position of the wheel unit, but it can also be used to determine other parameters.
